β¦ Synopsis
Background
Velocity-encoding generates small eddy currents causing background offset errors (recognised as velocity of stationary tissue). Chernobelsky et al. (2007) assessed background offset correction on 10 volunteers, demonstrating that offset errors β1% of VENC can cause up to 25% errors during measurements. No larger studies have yet measured this error.

## Abstract ## Purpose: To compare the utility of phase contrast MR imaging (PCβMRI) for assessment of pulmonary flow and pressure estimation with that of right heart catheterization and echocardiography (cardiac US) in patients with pulmonary arterial hypertension (PAH). ## Materials and Methods
## Abstract ## Purpose To assess the feasibility of using phase contrast magnetic resonance (PCβMR) imaging to measure the change in collateral blood flow early after stenting of aortic coarctation. ## Materials and Methods A total of 10 consecutive patients with coarctation of the aorta underwe
